Engine: Service Precautions
SUPPLEMENTAL RESTRAINT SYSTEM (SRS)1. Items to review when servicing SRS
1. Be sure to read Supplemental Restraint System (SRS). For safe operation, please follow the directions and heed all warnings.
2. Wait at least 60 seconds after disconnecting the battery cable before doing any further work. The SRS system is designed to retain enough voltage to deploy the air bag even after the battery has been disconnected. Serious injury may result from unintended air bag deployment if work is done on the SRS system immediately after the battery cable is disconnected.
3. Warning labels must be heeded when servicing or handling SRS components. Warning labels can be found in the following locations.
^ Front impact sensor
^ Sun visor
^ Glove box
^ SRS-ECU
^ Steering wheel
^ Clock spring
^ Joint cover . Air bag module (Driver's or front passenger's)
^ Seat belt pre-tensioner
4. Always use the designated special tools and test equipment.
5. Store components removed from the SRS in a clean and dry place. The air bag module should be stored on a flat surface and placed so that the pad surface is facing upward.
6. Never attempt to disassemble or repair the SRS components (SRS-ECU, air bag module, clock spring and seat belt pre-tensioner). If there is a defect, replace the defective part.
7. Whenever you finish servicing the SRS, check the SRS warning light operation to make sure that the system functions properly.
8. Be sure to deploy the air bag before disposing of the air bag module or disposing of a vehicle equipped with an air bag.
2. Observe the following when carrying out operations on places where SRS components are installed, including operations not directly related to the SRS air bag.
1. When removing or installing parts, do not allow any impact or shock to occur to the SRS components.
2. If heat damage may occur during paint work, remove the SRS components. After reinstalling them, check the SRS warning light operation to make sure that the system functions properly.
^ SRS-ECU, air bag module, clock spring: 93°C (200°F) or more
^ Seat belt pre-tensioner: 90°C (194°F) or more
SERVICING ELECTRICAL SYSTEM
WARNING: Battery posts, terminals and related accessories contain lead and lead compounds. WASH HANDS AFTER HANDLING
1. Note the following before proceeding with working on the electrical system.
Never perform unauthorized modifications to any electrical device or wiring. Such modifications might lead to a vehicle malfunction, over-capacity or short-circuit that could result in a fire in the vehicle.
CAUTION:
^ Before connecting or disconnecting the negative battery cable, be sure to turn the ignition switch to the "LOCK" (OFF) position and turn off the lights. (If this is not done, there is the possibility of semiconductor parts being damaged.)
^ After completion of the work (and the negative battery terminals is connected), warm up the engine and allow it to idle for approximately 10 minutes under the conditions described in order to stabilize engine control conditions, and then check to be sure that the idle is satisfactory.
^ Engine coolant temperature: 85 - 95°C (185 - 203°F)
^ Lights and all accessories: OFF
^ Transaxle: "N" position
^ Steering wheel: straight-forward position
2. When servicing the electrical system, disconnect the negative cable terminal from the battery.
VEHICLE WASHING
If high-pressure car-washing equipment or steam car-washing equipment is used to wash the vehicle, be sure to maintain the spray nozzle at a distance of at least approximately 40 cm (16 inches) from any plastic parts and all opening parts (doors, luggage compartment, etc. ).
APPLYING ANTI-CORROSION AGENT OR OTHER UNDERCOAT AGENTS
Be careful not to apply oil or grease to the heated oxygen sensor. If applied, the sensor may malfunction. Protect the heated oxygen sensor with a cover before applying anti-corrosion agent, etc.
SCAN TOOL (MUT-II)
CAUTION: Turn the ignition switch to "LOCK" (OFF) position before disconnecting or connecting the scan tool.
To operate the scan tool, refer to "MUT-II/MUT-II + Reference Manual."
SCAN TOOL (MUT-III SUB ASSEMBLY)
CAUTION: Turn the ignition switch to the "LOCK" (OFF) position before disconnecting or connecting the scan tool.
